lets_plot.scale_color_hue

lets_plot.scale_color_hue(h=None, c=None, l=None, h_start=None, direction=None, name=None, breaks=None, labels=None, limits=None, na_value=None, guide=None, trans=None, format=None)

Qualitative color scale with evenly spaced hues for color aesthetic.

Parameters
hlist

Range of hues (two numerics), in [0, 360].

cint

Chroma (intensity of color), maximum value varies depending on.

lint

Luminance (lightness), in [0, 100].

direction{1, -1}, default=1

Direction to travel around the color wheel, 1=clockwise, -1=counter-clockwise.

namestr

The name of the scale - used as the axis label or the legend title. If None, the default, the name of the scale is taken from the first mapping used for that aesthetic.

breakslist

A numeric vector of positions (of ticks).

labelslist of str

A vector of labels (on ticks).

limitslist

Continuous scale: a numeric vector of length two providing limits of the scale. Discrete scale: a vector specifying the data range for the scale and the default order of their display in guides.

na_value

Missing values will be replaced with this value.

guide

Guide to use for this scale. It can either be a string (‘colorbar’, ‘legend’) or a call to a guide function (guide_colorbar(), guide_legend()) specifying additional arguments. ‘none’ will hide the guide.

trans{‘identity’, ‘log10’, ‘sqrt’, ‘reverse’}

Name of built-in transformation.

formatstr

Defines the format for labels on the scale. The syntax resembles Python’s: ‘.2f’ -> ‘12.45’ ‘Num {}’ -> ‘Num 12.456789’ ‘TTL: {.2f}$’ -> ‘TTL: 12.45$’ For more info see https://lets-plot.org/pages/formats.html.

Returns
FeatureSpec

Scale specification.

Notes

Define qualitative color scale with evenly spaced hues for color aesthetic.
